Hello There,I print out the Softpedia instructions to install Ubuntu 9.10 on the same partition it is installed now, but it is not working because I can access the desktop after deleting the default NVIDIA drivers and installing the ones for Ubuntu 9. Now, I don't find answer to this question: "Do you want to unmount partitions?" I said not but later it could not proceed. I have XP Professional running in one partition and want to have dual booting as before. What are the consequences of unmounting partitions?I would appreciate very much your help!Regards,
